Addressing Crosstalk Issue in On-Chip Carbon Nanotube Interconnects Using Negative Capacitance

Increasing Crosstalk is one of the most critical concerns for on-chip signal communication in nanoscale integrated circuits. This paper presents a method to use the negative capacitance technique to minimize crosstalk effects in carbon nanotube based interconnect, which is a potential future on-chip communication medium. With some assumptions, it is demonstrated that with careful synthesis and arrangement of CNT bundles, the capacitive coupling can be suppressed significantly. The focus of this paper is proving the concept, and the analysis is from mathematical and qualitative perspective. Its practicality depends on the success in synthesis and manufacturing of CNT in actual IC environment. In the context of current interests and progresses in CNT research it can be inferred the implementation challenge can be overcome in future.
